Boron Nitride
Thermally Conductive, Electrically Insulating, Highly Lubricious
Boron Nitride fillers from 3M™ offer a way of dramatically increasing thermal conductivity of polymer composites. Finished parts can achieve up to 10 W/mK in-plane and 4 W/mK through-plane. As a material it is highly electrically insulating and lightweight, certainly benefiting select applications in electronics and transport. Miniaturization of electronic components and a rapid growth in electric battery technologies have been key drivers in the success of this material, although these are just two sectors amongst a diverse range of use cases.
Boron nitride is also widely used in high temperature lubrication applications, including where incidental food contact is required.
3M™ offer a unique range of platelets, flakes and agglomerates - each suited to a different application. Get in touch with the technical sales team at Lawrence Industries to see how we can help with your thermal conductivity project.
